It comes out while assessing the focus that execution of the rules was essential increasingly whereat it may harm Islam in the preliminary juncture because of the extreme enmity against Islam but the reason for the slow and steady implementation is offered by the example of seed which has all persona of a tree but gradually.

            Further, man is a part of whole, called by us universe. The aspects of universe are two, spiritual and material. Because, Islam is a universal religion, and the universality of the universe is present in Islam. The spiritual aspect of universe and the faith aspect of Islam will linger constant up to the Last Judgment and life hereafter as well. The matter of grasping side of universe is dissimilar.

            This side of universe appeared steadily and is variable momently and will culminate one day for the cause of changeability. On the same prototype, the principles of Islamic economy were implemented. If the culmination of Caliphate and the initiality of Mulukyat had not happened, the economic principles would have remained changeable.

Supposingly, the scientists claim that the earth we live on was ablaze mass of fire. If it is true, there were only thermodynamics principles. Then they claim that it began to cool steadily even it began to rain. If this theory is admitted, then the rules would be of metrological and then botanical and on the birth of human and animals, the rules of zoological would be implemented. Then, it has to admit that all such rules were present in the Holy Book. On the same pattern, the principles of economy had been already present in the Holy Book, the Quran and the Sunnah. For the validation of this subject, an example of slavery is adequate.
